Turn usernames into permanent, programmable on-chain identities. The missing identity layer for Web3 users, apps, games, and agents.
Web2 usernames are controlled by platforms. They can be deleted, recycled, impersonated, or lost when a platform changes its rules. Users don't own their identity.
Web3 wallets solved ownership, but addresses like 0x1D187Aa2...017a aren't human-readable. They're impossible to remember, discover, or trust.
Persistent Identity Protocol bridges this gap.
Any Web2 company can transition their username system to Web3 identity. No blockchain expertise required. Your existing login system keeps working.
Your users take their identity with them. username.yourbrand.gg works across games, apps, marketplaces, and social platforms. Your brand travels with every user.
Complete username history immutably stored on-chain. No more database tampering, no disputed account ownership, no recycled usernames. Every change is auditable.
Users can verify each other's identity age, ownership history, and reputation signals. On-chain identity makes impersonation harder and trust easier.
Users keep logging in with username + password or email + magic link. The identity upgrade happens behind the scenes. Zero friction for existing users.
Users can own multiple identity names and log in with any of them. A gaming handle, a professional alias, and a brand page, all pointing to the same account.
Your identity namespace becomes infrastructure. Partner projects can accept your identity tokens for login, giving your users access to an expanding ecosystem.
Economic pricing on identity registration creates natural spam resistance. No more armies of fake accounts. Real users, verified on-chain.
Every identity can have a canonical URL record on-chain. username.peg.gg redirects to whatever the user sets. Profile pages, portfolios, social links, all decentralized.
Persistent Identity is powering the identity migration for Pentagon.games, a Web3 gaming ecosystem with 685K+ users.
Type any name. AI scores it in seconds based on rarity, cultural significance, and web presence.
Pay in PC. Your name is minted as an NFT on-chain. You own it.
Bind to your wallet. Set your forward URL. Log in with your name. You're live.
Any dApp resolves @yourname to your wallet. No DNS. No middleman. Trustless.
yourname.peg.gg is your profile. One identity, everywhere in the ecosystem.
Set any URL. Visitors to yourname.peg.gg get redirected. On-chain source of truth.
Bound identities can't be stolen or sold. Unbind only through governance to trade.
AI agents get the same identity. Human-to-agent and agent-to-agent, all by name.
Launch your own namespace. Your brand, your rules, your identity system.

Persistent Identity Protocol is being submitted as an ERC standard. PEG ID is the first reference implementation. The protocol is chain-agnostic and designed for white-label adoption.
